Sorry, online ordering is unavailable…

Repeatedly receiving “Sorry, online ordering is unavailable to this destination and/or weight. Please double check your destination details.” even after following advice for store setup found here: http://getshopped.org/resources/faqs/#Shipping2

Store URL: http://relationshipmodel.com/products-services
WordPress version:3.8
WP e-Commerce version:3.8.12.1
Gold Cart version: 2.9.7.6
Theme: Website theme (themeforest)

I did this:
— set up wp e-commerce store with gold cart plugin & third party premium shipping plugin
— followed all advice found here: http://getshopped.org/resources/faqs/#Shipping2
— deactivated third party shipping plugin to see if it was causing the error. error still occurred.

I expected WP e-Commerce to do this: work for ordering items

Instead it did this: gives message “Sorry, online ordering is unavailable to this destination and/or weight. Please double check your destination details.”
